Abstract: An engine system includes an engine, an intake line, an exhaust line, a turbocharger, a water-cooled intercooler, a high-pressure Exhaust Gas Recirculation (EGR) system which includes a high-pressure EGR line, a high-pressure EGR cooler, and a high-pressure EGR valve, a low-pressure EGR system which includes a low-pressure EGR line, and a low-pressure EGR cooler, a radiator which cools the coolant, a low-pressure EGR cooling line, an intercooler cooling line, a low-pressure EGR cooling valve, an intercooler cooling valve, an electric water pump, a driving information detector which detects driving information of a vehicle including an outside air temperature, a temperature of the intake gas supplied to the engine and a coolant temperature, and a controller which controls the low-pressure EGR cooling valve, the intercooler cooling valve, the high-pressure EGR valve and the electric water pump based on the driving information detected by the driving information detector.
